What does the turbine do in a torque converter?
What does the turbine do in a torque converter?
The torque converter casing connects to the flywheel, spinning at the same rate as the crankshaft, within the housing of the turbine. The impeller or centrifugal pump effectively flings the transmission fluid into the fins of the turbine that in turn spins or transmits the torque into the transmission.
How does a torque converter work in a turbine?
Detail of Torque Converter Components EXPLANATION OF HOW IT WORKS/ IS USED: Detail of Torque Converter Components Power is applied to the input shaft, and in turn, the impeller. The torque and angular velocity of the impeller sets the fluid in circular motion throughoutthe shell. Circulating fluid applies a force on the turbine fins.
What causes a car to spin in a torque converter?
The turbine causes the transmission to spin, which basically moves your car. You can see in the graphic below that the blades of the turbine are curved. This means that the fluid, which enters the turbine from the outside, has to change direction before it exits the center of the turbine.
How is the turbine connected to the output shaft?
The turbine is connected to the output shaft. The reactor is “grounded” (meaning rigidly connected)to the casing by means of a one-way clutch. Detail of Torque Converter Components EXPLANATION OF HOW IT WORKS/ IS USED: Detail of Torque Converter Components Power is applied to the input shaft, and in turn, the impeller.
What are the efficiencies of a torque converter?
Torque converters run at efficiencies anywhere from 0-95% depending on w ( in), w ( out), and T (in) and T (out). For example, when a car is stopped at a traffic light, the engine still applies power to the input shaft, but the brakes and transmission prevent the output shaft from rotating.
What causes a torque converter turbine to spin?
This means that the fluid, which enters the turbine from the outside, has to change direction before it exits the center of the turbine. It is this directional change that causes the turbine to spin. The torque converter turbine: Note the spline in the middle.
How is the torque converter connected to the transmission?
The turbine is not mechanically connected to the impeller (in the absence of an applied lockup clutch), but spins entirely from the inertia of the whirling oil. The turbine shaft splines directly to the input shaft of the transmission, turning whichever clutches and gears are hydraulically engaged in the transmission itself.
How does a stator work in a torque converter?
The stator sends the fluid returning from the turbine to the pump. This improves the efficiency of the torque converter. Note the spline, which is connected to a one-way clutch inside the stator. The stator resides in the very center of the torque converter. Its job is to redirect the fluid returning from the turbine before it hits the pump again.
How does a torque converer work at MIT?
GEOMETRY/STRUCTURE: The entire unit resembles a donut shaped housing, with a hollowed interior. The turbine and impeller units resemble donut halves, and are lined inside with fins. Detail of Torque Converter Components The impeller is connected to the input shaft.
